This package contains many tools for statistical analysis. It was programmed from 1994 and served as pseudo-official tool for a few engineering students at the UCL. It was developed to fit in an HP 48G and to that effect has been compressed. You will need the RF compressor and the RFPU utility to decompress the programs (see author's website).

Allows one to solve root finding approximation problems using various methods: Newton, secants, bisection, "regula falsi" (known as "false position") and successive approximations. The peculiarity of this program is that it display all the iterations (not just the solution!) with the number of significant digits chosen by the user.

CMAT is an HP 48 program for performing operations on columns of a matrix. CMAT iterates over each row of the matrix, treating the n columns of the matrix as if they were variables named C1, C2, ... Cn, or, optionally, as if they were named with user-specified names.

This program allows to solve a differential equation system usng the 4th order Runge-Kutta method. It´s perfect for the Chemical Reaction Engineering course and some Electrical Engineering applications.

Performs discrete trapezoidal integration, and is essentially a "waveform integrator", where the input can be considered a waveform consisting of data points defined by the input vectors Y (dependent) and X (independent).

This package contains a CST menu and an installation guide. It is a mathematics program that includes, a table of values, a 'suites' manager, a PPCM-PGCD calculator, a 'bac' marks calculator, and a 'number decomposer'.

System RPL and machine language library with linear- tabular- and double interpolation, cubic splines, linear predicting, and second and third order least squares polynomial fitting. Accepts many combinations of input. Also tested on 49g+ ROM 1.23.

This package contains many, many numerical methods for root finding, linear systems, differential equations, etc, etc,... It was programmed from 1993 and served as pseudo-official tool for most engineering students at the UCL for a bit less than 10 years. It was developed to fit in an HP 48G and to that effect has been compressed. You will need the RF compressor and the RFPU utility to decompress the programs (see author's website).

User RPL program for the 48G/GX that finds equation roots by three numerical methods: Newton Raphson, False Position and Bissection. It shows the approximation, last approximation, error approximation and precision/iteration at each iteration. It also checks the roots found and calculates the number of precision numbers and number of correct digits for a pair of numbers. Might be useful for numerical calculus students.

Allows you to choose to calculate any one side of a right triangle, or enter all of the side lengths of a triangle to find if it is right. In User RPL for easy editing and compatibility with the 49 and 48.

A User RPL program to calculate the vertex, roots, discriminant, and completed square [or standard form] of a quadratic equation using given coefficients. Gives exact values (on the HP 49 only) if desired.

Do you need to calculate the integer solutions of a polynomial equation? This is the program you can use. It was created as the final project of System RPL programming given in the Civil Engineering school of Granada.

Tiny MSLV (multiple equation solver) for all RPL calculators. Program is 333.5 bytes on the 48GX. On the HP-28C it can find a simultaneous root of five nonlinear real-valued expressions. Uses successive approximation and the calculator's built-in matrix functions.

Here are 3 programs that give numerical results to: any angle between two vectors by cross product or dot product and a program that finds the projection vector length (or the component vector length) whatever floats your boat.
